BOOK-BINDING.

SPECIFICATION,forming part of Letters Patent lNo. 286,634, dated October 16, 1883.

, Application filed april 27, lSSQ. (Mullvl.)

Be it known that I, LANDON R. GooniuN,

of the city of New York and State of New York, have invented a new and useful Improvement in Boolelinding; and I do hereby declare that the following is a full, clear, and exact descrip tion th ereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. p

Figure l of the drawings represents a plan view of the cover or lids of a book with my improved binder-fastening attached. Fig. 2 .represents a longitudinal section of the same with the leaves or paper secured thereto. Fi I 5 3 is atransverse section of the same without the leaves. Fig. 4 represents one of thelugs of the binder and its eateh detached, and Fig. 5 represents a transverse section ofthe binder and cover with a metal spring for clamping the leaves 2o of paper or the body of a book secured therein. Fig. 6 represents a crossseetion, on an enlarged scale, of the binder-rod, showing it covered with a tube or coat of india-rubber. Fig. 7 represents a crosssection of the binder, show- 2 5 ing a construction thereof specially adapted to holding single sheets of paper.

Like letters designate corresponding parts in all of the figures.

' The object of my invention is to provide a 3o self-adjusting book-binder which will secure separate sheets of paper in the forni of abook of any desired thickness, and which will allow the removal of the paper constituting the book, or any number of the sheets or leaves compos- 3 5 ing it, and be capable of securely retaining any number' of sheets or leaves until they are from time to time exhausted or used, the purpose being to furnish for commercial use a bookbinder especially adapted for bills, tally-sheets, 4o memoranda, and other similar papers which are required to be detached and used separately from time to time in their integrity; and my invention constitutes an improvement upon the invention patented by Charles F. Me- Gill, November 7, 1876, which patent is numbered 184,094, as my said improvement embraces self-adjusting features herein described. That invention embraced a catch and bindingrod which permittedv the insertion of a book 5o or bulk of paper that was thereby secured to a cover; but a removal of a portion of the book 'to the central iiexible part ofthe cover.

or sheets of paper would cause the remaining portion to become loose and liable to slip out of the fastening or binder, while on the other hand my self-adjusting binder will act to retain the sheets or leaves until all are used, when the binder is ready to receive and hold securely a new supply of any desired quantity.

In the drawings, c denotes the cover, b the leaves, of the book; c, the thin metal plate or 6o base of the binder, riveted or otherwise secured d d are the lugs or uprights of the binder, one of y which may be hinged, as shown at w, Fig. 5.

c is the binder-rod secured to lug d. f is the catch formed in lug d, for holding the binderrod in place while securing thebook or leaves b; and gis a tubular rubber spring, fastened longitudinally upon the base-plate ofthe binder by the Vwire fi, which passes through the rubber tube 7o and through holes in lugs d fl', where it is secured by any suitable means, as shown in Fig. 3. This springf/ lls the space between the binderrod e, and the base or back ofthe binder, and compensates for the withdrawal of any num- 7 5 ber of sheets or leaves from the binder, adapting the space also to any number of leaves, whether few or many. It is therefore an essential part of my invention. rlhe ring o may be used as a means of suspending the bound 8o book when used in an oflice; but when carried in the pocket the ring will not be required.

'The binder-rod e is suflieientlyelastic to retain its place in the hook or catch f, and when any quantity of paper is to be placed in the binder, rod e will be moved laterally from the catch f, and, whether secured at its opposite end to a rigid or to a hinged lug, will yield sufficiently to permit the book or body of pa- Vper to be inserted below it upon the retaining 9o rod e may be used, as represented in Fig.7. Forholding single sheets of paper, this grooved rubber is preferable for the compensatingspring, since it produces also friction on the.

, substance, like a rubber tube, as sh own in Fig.

6, which furnishes a good frictional surface, and likewise furnishes a compensating spring or material to a certain extent.

Having described my invention, I claiml. The combination, with the binder-roi,

of a grooved rubber compensating-spring, substa-ntially as and for the purpose herein specified.

2. In a book-binder, the combination, with afbinding-rod, e, and base c, of a compensatingspring, g, located between the said parts, substantially as and for the purpose herein specified.

3. The combination of the base c, provided with two lugs, d d, the binder-rod e, attached to one lug, d, and held by a hook, f, on the other lug, (l, and the compensating-spring g, substantially as and for the purpose herein specified.

4. In combination with the base c and co1npensating-spring g, the binder-rod c, surrounded by an elastic material, substantially as and for the purpose herein specified.
